[ruby/reline] Separate prompt and input line in rendering

Browse source 
(https://github.com/ruby/reline/pull/652)

* Separate prompt and input line in rendering

Often, only one of prompt and input changes.
Split prompt+input_line to a separate rendering item will improve differential rendering performance.

* Rename method wrapped_prompt_lines to more descriptive name
